DESCRIPTION (provided by applicant): Alcohol use within the college student population is both widespread and problematic1,2,3. There are many negative consequences associated with frequent alcohol use, ranging from mild (e.g., hangovers, missed classes) to severe (e.g., DUIs, assault, death)4,5. Popular online interventions targeting alcohol use among college students reduce alcohol consumption and associated problems6,7. However, online interventions are not as efficacious as face-to-face interventions8. The proposed project will employ emailed boosters in a randomized, controlled trial in an effort to improve the efficacy an existing, popular, free online intervention, Alcohol 101 PlusTM9, while at the same time maintaining low cost and easy dissemination. Boosters have been used successfully for alcohol use interventions among those seeking injury treatment in emergency medical settings10,11,12. Despite these successes, prior research has not supported booster efficacy for college student alcohol interventions6,13. The proposed project seeks to develop and evaluate the effectiveness of boosters for a widely-used college student alcohol intervention by improving on the design of boosters. Specifically, the present project will improve boosters by providing easy access via email to minimize burden; providing succinct, personalized feedback; and providing reminders of protective behavioral strategies (PBS). PBS have consistently predicted reductions in alcohol-related problems1,14,15,16. The proposed study will critically examine the issue, including the manipulability of PBS use. The online intervention includes PBS as one component of education, and proposed boosters target these behaviors specifically. The proposed research will address the following specific aims: Aim 1: Improve the efficacy of an easily-disseminated computerized intervention by adding personalized follow-up boosters, where efficacy is evidenced by reduced drinking and related problems. Aim 2: Extend the duration of the reduction in drinking and associated problems through the use of these personalized follow-up boosters. Aim 3: Examine protective behavioral strategies highlighted by the intervention as mediating behavioral mechanisms of change. Experimental Protocols: Participants will be assessed on key constructs, then will be randomized to receive the intervention or not. To test the effectiveness of adding boosters, participants randomized to alcohol intervention boosters will receive emails 4 weeks after the intervention with tailored feedback based upon their reported alcohol consumption after the intervention. Participants will initially be assessed biweekly, then every three months up to nine months. Significance: The proposed study will be a critical first step in launching a programmatic line of research to adapt existing online interventions and develop future interventions that include PBS as a major program component. The findings from this study will be used to identify implications for modifying the protocol or booster. These will drive the hypotheses for subsequent studies in this program of research. PUBLIC HEALTH RELEVANCE: The goal of the proposed research is to examine whether an innovative booster can strengthen and extend the effects of a computerized intervention targeting college drinking. The booster is low-cost and easy to disseminate, thus implementable on a large scale. Consequently, the public health impact may be far-reaching.

描述（由申请人提供）：大学生人数中的饮酒既普遍又有问题1,2,3。频繁使用饮酒会产生许多负面后果，从轻度（例如宿醉，错过的班级）到严重（例如DUIS，DUIS，攻击，死亡）4,5。针对大学生饮酒的流行在线干预措施减少了饮酒和相关问题6,7。但是，在线干预措施不如面对面干预8。拟议的项目将在随机，对照的试验中采用电子邮件的助推器，以提高现有的，受欢迎的，免费的在线干预，酒精101 plustm9的功效，同时保持低成本和易于传播。在紧急医疗环境中寻求伤害治疗的人中，助推器已成功用于酒精使用干预措施10,11,12。尽管取得了这些成功，但先前的研究并未支持增加大学生酒精干预的助推器功效6,13。拟议的项目旨在通过改进助推器的设计来开发和评估助推器对广泛使用的大学生酒精干预的有效性。具体而言，本项目将通过电子邮件提供轻松访问以最大程度地减轻负担来改善助推器；提供简洁的个性化反馈；并提供保护性行为策略（PBS）的提醒。 PBS一直预测与酒精有关的问题减少1,14,15,16。拟议的研究将严格研究该问题，包括PBS使用的操纵性。在线干预措施包括PBS作为教育的一个组成部分，并提出了专门针对这些行为的助推器。拟议的研究将解决以下特定目的：目标1：通过添加个性化的后续助推器来提高易于删除的计算机干预的功效，在这种后续助推器中可以通过减少饮酒和相关问题证明疗效。目标2：通过使用这些个性化的后续助推器来延长饮酒和相关问题的减少持续时间。目标3：研究干预措施强调的保护性行为策略是介导的行为机制。实验协议：将对参与者进行关键构造的评估，然后将随机分配以接受干预。为了测试增加助推器的有效性，参与者在干预后4周将随机分配给酒精干预助推器，并根据干预后的量身定制反馈，根据他们的干预后的饮酒。最初将每两周对参与者进行评估，然后每三个月至9个月进行一次评估。意义：拟议的研究将是启动程序性研究线以适应现有在线干预措施并制定包括PBS（PBS作为主要程序组成部分）的未来干预措施的关键第一步。这项研究的发现将用于确定修改协议或助推器的含义。这些将推动该研究计划中随后研究的假设。 公共卫生相关性：拟议研究的目的是检查创新的助推器是否可以加强和扩展针对大学饮酒的计算机干预的影响。助推器是低成本且易于传播的，因此可以大规模实施。因此，公共卫生影响可能是深远的。
